Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484526, here are decompositions:

13 + 31484513 = 31484526
23 + 31484503 = 31484526
109 + 31484417 = 31484526
113 + 31484413 = 31484526
149 + 31484377 = 31484526
163 + 31484363 = 31484526
167 + 31484359 = 31484526
173 + 31484353 = 31484526

Showing the first eight; more decompositions exist.
